UNITED STATES PATENT OFFICE.

WILLIAM G. CONKLING, OF GIJENS FALLS, NEIV YORK.

ORE-SEPARATOR.

SPECIFICATION forming part of Letters Patent No. 464,816, dated December8, 1891.

Application filed September 19, 1889- Renewed June 20, 1891- Serial No.396,885 (No model.)

To all whom it may concern.-

Be it known that 1, WILLIAM G. OONKLING, a citizen of the United States,residing at Glens Falls, in the county of Warren and State of New York,have invented new and useful Improvements in Apparatus for SeparatingOre and other Substances, of which the following is a specification.

This invention relates to that type of apparatus for separating orewherein magnets arelocated within an endless imperforate belt; and theobject of the invention is to provide novel means whereby the pulverizedmass is prevented from running off the longitudinal edges of the beltand the tendency of the mass to deepen and overrun the edges of the beltwithin the field of the magnets is counteracted.

To accomplish these objects my invention involves the features ofconstruction, the combination or arrangement of parts, and theprinciples of operation hereinafter described and claimed, referencebeing made to the accompanying drawings, in which- Figure 1 represents aplan or top view. Fig. 2 is a transverse vertical section in the plane5c 00, Fig. 1.

Similar lettersindicate correspondingparts.

In the drawings, the letter Adesignates an endless belt, which extendsround the rollers B B and which is made of any suitable flexiblematerial, such as leather, india-rubber, or canvas, india-rubber clothbeing used by preference. If a pulverized substance-such as pulverizedore-is fed onto the belt at or near the roller B,so that the same iscarried away by the belt in the direction indicated by the arrows inFig. 1, said pulverized mass has a tendency to run off toward the edgesof the belt, and if the belt is provided with raised rims the pulverizedmass has a tendency to form a deep layer toward both edges of the beltand even to run over the raised rims. In order to counteract thistendency, I have applied two aprons C C, which are firmly secured to anddepend from the frame D and are placed edgewise toward the belt with aslight inclination, so that the pulverized mass is prevented fromrunning over the edges of the belt. These inclined pendent aprons C havetheir lower edges located between the longitudinal edges of the onecarrying-belt, and such lower edges of the aprons are parallel to anddirectly above the traveling upper side or surface of the belt and insuch juxtaposition thereto that the two edges of the belt project,respectively, beneath the lower edges of the two aprons, but the orewill not pass between.

In some cases it is desirable that the pulverized mass carried by thebelt shall be directed from the edges of the belt toward the middlethereof, and in order to effect this purpose the aprons O O are curvedinward. This form of the aprons is indispensible if the carrying-belt isused in combination with magnets F F, which extend in the direction ofthe length of the belt, as indicated in dotted lines in Fig. 1 and insection in Fig. 2.

WVhat 1 claim as new, and desire to secure by Letters Patent, is.

In a magnetic ore-separator, the combination of the frame D, the rollers13 B, the endless imperforate belt A, the magnets F F, and the pair ofinclined aprons C O, secured di' rectly to and depending from the sidesof the frame, with their lower edges located between the twolongitudinal edges of the belt, said pendent aprons running parallelwith the upper moving surface of the belt and curved inward toward eachother across the belt and within the field of the magnets,substantiallyas shown and described.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
